RT Journal Article SR Electronic T1 Convergent Validity and the Time Consistency of Preferences: Evidence from the Iowa Lakes Recreation Demand Project JF Land Economics JO Land Econ FD University of Wisconsin Press SP 269 OP 291 DO 10.3368/le.93.2.269 VO 93 IS 2 A1 Yi, DongGyu A1 Herriges, Joseph A. YR 2017 UL http://le.uwpress.org/content/93/2/269.abstract AB We examine the consistency of preferences over time and as implied by revealed versus stated preference (contingent behavior) data. Studies in this area are typically based upon a single site and focus on consumer response to changes in travel cost or site access. We use data from the Iowa Lakes Project, which provides information on usage patterns over several years and for 132 lakes, along with detailed water quality data. This allows us to test for convergence in how individuals respond to changing site characteristics, as well as the consistency of preferences over time and between actual versus contingent trips.
